Question? Thought? Discussion? Possible bolt on turbo manifold with td03 turbo???

the cylinder wall thickness is very very small, looks like a millimeter the pistons arent very beefy either. The rod ratio is something like 1.5:1 so I believe theres a little potential to rev but I really wouldnt push it without doing some internal work. I uploaded a couple pics a while back on the 3a92 thread.

The chart is not mine, but there's some serious high revving motors (7k+) on that list that make more than enough power with similar rod ratios.

I wouldn't loose faith, the piston dwell time becomes less important as boost rises, anyhow. Sorry I can't get the chart right. I think your on the right track researching the head, looking specifically at different cam profiles. I bet it flows very well "from the box"


Has anyone confirmed, or discounted the smart turbo manifold as a bolt on gig? It shares the same block, and its turbo?

Wanted to bump this thread, anyone make any headway with a turbo option?

You should ask the new guy from Puerto Rico, he is running a turbo on his Mirage.

The OEM manifold...... It looks exactly like a LOG style turbo manifold, except it mates up to the catalytic converter.



Not to steal their image, but look closely. CHOP the pipe right above the mounting point, weld in a turbo flange for mounting. DONE. Manifold complete. And would be cheaper than pretty much every other method. That part of the manifold is like 20 or 30 bucks last I checked. Now if you wanted something more custom, go for it, but I'm a cheap ****.....



Stole this image from another thread. Chop, add turbo flange, add turbo, fin. Might not flow as good as a custom unit, but for starters its not a bad method.

This has probably already come up, but has anyone investigated the turbo three-cylinder Mitsu engine from the Smart Fortwo? It makes 89 hp.
